摘要 目的对肌红蛋白(Mb)、肌酸激酶同工酶(CK-MB)和心肌肌钙蛋白I(cTnI)单项定量检测及联合检测进行比较,为急性心肌梗死(AMI)的早期诊断和预后评估提供更准确合理的检测指标。方法对239例临床征象高度可疑的AMI患者在入院后24h内检测cTnI、Mb和CK-MB,比较它们对AMI诊断的敏感性和特异性,并进行组合。结果在入院后24h内cTnI、Mb、CK-MB对AMI的敏感性分别为96.8%、100%和76.6%,特异性分别为100%、89.4%和97.6%。AMI患者死亡率随着cTnI水平的升高而显著增加。cTnI、Mb、CK-MB联合检测,对AMI的敏感性为100%,特异性为88.2%,阳性预期值为100%,阴性预期值为84.2%。结论cTnI、Mb和CK-MB联合检测,结果其敏感性提高到100%,阳性预期值达100%,其综合特异性也可达88.2%,同时对预后、再梗死发生及疗效有很好的观察效果。
